Problem:
QuerySeeds will poke 150 random entries in the whole node DB and ignore hitting "field" entries.
In a bootstrap scenario it might hit hundreds of :lastping :lastpong entries,
and very few true "node record" entries.
After running for 15 minutes I've got totalEntryCount=1508 nodeRecordCount=114 entries.
There's a 1/16 chance of hitting a "node record" entry.
It means finding just about 10 nodes of 114 total on average from 150 attempts.
Solution:
Split "node record" entries to a separate table such that QuerySeeds doesn't do idle cycle hits.
UpdateFindFails/UpdateLastPingReceived/UpdateLastPongReceived events
are causing bursty DB commits (100 per minute).
This optimization throttles the disk writes to happen at most once in a few seconds,
because this info doesn't need to be persisted immediately.
This helps on HDD drives.
Encode and hash logic was duplicated in multiple places.
* Move encoding to p2p/discover/v4wire
* Move hashing to p2p/enode/idscheme
* Change newRandomLookup to create a proper random key on a curve.
If --nat extip:1.2.3.4 option is specified, the port mapping logic
(AddMapping/DeleteMapping) does nothing.
This optimization avoids running a goroutine for doing nothing.
Extract private key setup from the global config setup to make it reusable.
Return errors instead of panicing.
* NodeKey() method is removed - it is unused.
* use "log" for struct fields
* use "logger" for function parameters and local vars
This is a compromise between:
1) using logger := log.New() to avoid aliasing (log := log.New())
2) and keeping it short when logging e.g.: srv.log.Info(...)
